Your computer http://h18002.www1.hp.com/products/quickspecs/1163... seems to have a NVIDIA Quadro4 100NVS AGP x4, so you have to look for another AGP x4 video card HDTV ready.

AGPx4 video cards are for older computers, but they still can be found in stores (there are some compatible with both AGP 8x and 4x). Here's an example (from tigerdirect.com, where I buy most of my computer related items): http://www.tigerdirect.com/applications/SearchTool...

Your desktop PC being able to house a new, stronger video card will depend largely on whether or not your Power Supply Unit (PSU) can provide enough energy to power that new video card. Looking at the wattage of your PSU is an indicator, but some low-watt PSU's can power strong video cards despite havnig low wattage (such as 300 or so). The safest way to tell if your PC can power a more powerful video card is by looking at the newer models of the HP Envy, see which video cards work with that, then comparing that PSU to your PSU. If you have the same PSU or atleast the same specs, your computer will be able to run that video card too.

You can get a PCI Graphics card from newegg.com that is about the only one that will work, I am not sure if your motherboard has an AGP Slot, but im positive it does not have PCI Express, so look on newegg for a standard PCI graphics card

if it's that crappy little mini case, you might be SOL. Don't know why anyone would want a computer with a case like that. You might look into buying another case so you can fit a better video card inside it.

There is no PC case that dissalows a card, but rather the motherboard. check which ports you have, and go to tigerdirect.com good cardsthere and YES most are HD compatable(check product description)
